My carrier anticipated the return flight by 6 hours, destroying my last day of the trip, BUT the carrier offered Kiwi a refund writing to the email address the create for your booking (I know this because the airline confirmed it to me themselves, and other friends who booked the same flight directly with the airline got the refund). Although Kiwi policy says that, in such a case, FOR ALL FARES they will offer you the chance to take the refund or accept the change, THEY NEVER GAVE ME this chance and refused to give my money back. They insisted in treating my request as voluntary cancellation. So do not trust in what is written on their website, they will just rob you.
